Revealing mistake: When the 'snow ram' loses power and stops, the crew jumps out to see what has happened. The snow surface behind the ram is undisturbed and trackless, as if the ram has been stationary long enough for its tracks to be erased. This is because it is actually on a set and has not moved at all.

Commander Adama: Mr. President, a wall of unidentified craft is closing in on the fleet.Baltar: Possibly a Cylon welcoming commitee.Commander Adama: Sir, may I suggest we launch a 'welcoming commitee' of our own?

When Baltar turns to face the two setting suns, we see the lower one at the left has what could be a boat in its reflection on the water. The higher one on the right is over a mountainous area on the horizon. The next shot is of Baltar in close-up, then the next returns to the horizon to show us Baltar's view, which shows just ONE setting sun. The one on the left has vanished though there is room enough for it to have been seen in this shot.
